When New England was hit by Tropical Storm Irene in 2011, there was not a satellite monitoring tropical storms that far north; the Tropical Rainfall Measuring Mission (TRMM) was operating in a band between the 35-degree latitudes. The Global Precipitation Measurement (GPM) mission will change that. GPM will build upon TRMM's capacity by examining a larger swath of Earth with instruments that are more advanced and more sensitive. This video introduces the GPM satellite, its instruments and their capabilities.

Like Earth, Mars has valleys that seem to be caused by a flowing fluid, presumably water. One can see dendritic drainage patterns as well as flood channels on the Martian surface. This module focuses on whether the channels observed on Mars are evidence of great floods and, if so, on how Pathfinder helps scientists to use the debris from such floods to obtain information about four billion years of Martian geologic history.

So, what's the difference between "weather" and "severe weather"? Is it just how hard the wind is blowing? Is it just thunder and lighting? Well, it can be some or all of those things. In this episode of Crash Course Kids, Sabrina talks to us about what makes Severe Weather and how it interacts with the Geosphere and Biosphere.

In this episode of Crash Course Kids, Sabrina gives us a real world example of how the Hydrosphere and Geosphere affect each other in the form of Weathering and Erosion. Think of Weathering as the force that makes a mess and Erosion as the force that cleans it up.
